INSTA WEATHER PLUS FORECAST WITH TONY PANN. WE WILL TALK ABOUT ARTHUR IN JUST A MOMENT. THIS AFTERNOON, THE HEAT AND THE POSSIBILITY OF THUNDERSTORMS. TEMPERATURES, 90 AT THE AIRPORT, SAME THING IN WESTMINSTER. THE DEW POINT IN THE LOW TO MID 70'S, IT HAS A TROPICAL FEEL. THAT WILL PUSH THE HEAT INDEX, WHAT IT FEELS LIKE COME CLOSE TO 100 OR SLIGHTLY OVER, ESPECIALLY AROUND BALTIMORE. RIGHT NOW, IT FEELS LIKE 99 DOWNTOWN AND 98 IN PARKTON. HE READY FOR THE HEAT. AIR QUALITY IS GOING TO BE IN THE PORTER RANCH, IF YOU HAVE RESPIRATORY PROBLEMS KEEP THAT IN MIND. IN THE HEAT AND HUMIDITY, THE ATMOSPHERE COULD HAVE A CHANCE FOR SEVERE WEATHER UP AND DOWN THE I-95 CORRIDOR. SEVERE THUNDERSTORM WATCH IN EFFECT FOR MOST OF PENNSYLVANIA, I SUSPECT IT WILL BE ISSUED IN MARYLAND OVER THE NEXT COUPLE HOURS. NOTHING REALLY HAPPENING AROUND BALTIMORE RIGHT NOW, BUT WE CAN ALREADY SEE SOME THUNDERSTORMS DEVELOPING IN THE MOUNTAINS, ALLEGHENY COUNTY AND WASHINGTON COUNTY AND SOUTHERN PENNSYLVANIA. THAT WILL DRIFT TOWARDS BALTIMORE OF THE NEXT FEW HOURS. PROBABLY UP UNTIL ABOUT 2:00 WE WILL BE OK AROUND THE CITY. AFTER THAT, WATCHING FOR THE POSSIBILITY OF BIG THUNDERSTORMS. SPEAKING OF BIG STORMS COME HERE IS ARTHUR. LOOKS A LITTLE BIT MORE HEALTHY ON THE SATELLITE IMAGERY. LOOKS LIKE IT'S GETTING AN EYE, THUNDERSTORMS ARE WRAPPING AROUND THE CENTER. IT IS NOT A TROPICAL STORM WITH SUSTAINED WINDS OF 60 MILES PER HOUR, IT WILL BECOME A HURRICANE LATER TODAY OR TOMORROW. THE FORECAST AS A 11:00 A.M. TAKES IT UP OFF THE NORTH CAROLINA COAST BY THURSDAY NIGHT AND FRIDAY MORNING AS A CATEGORY ONE HURRICANE. THE BIG QUESTION IS WILL AFFECT THE BEACHES IN MARYLAND AND VIRGINIA? LOOKS LIKE IT WILL STAY OFFSHORE SO WE WILL NOT HAVE A DIRECT IMPACT AT THE DELMARVA BEACHES. IF YOU ARE GOING TO THE BEACH, YOU WILL FEEL SOME STUFF, ESPECIALLY TOMORROW AND FRIDAY MORNING. SHOWERS AND THUNDERSTORMS COULD BE HEAVY AT OCEAN CITY. THE SURF WILL BE PAID TO, THE RIP CURRENT RISK WILL BE HIGH. A WINDY DAY FRIDAY, OVER 40 MILE-PER-HOUR GUSTS. SHOULD CLEAR UP ON FRIDAY AFTERNOON. SATURDAY AND SUNDAY LOOK BEFORE. IF YOU'RE GOING FOR THE WEEKEND, THURSDAY AND FRIDAY MORNING WILL BE ROUGH BUT AFTER THAT IT SHOULD BE OK. THAT IS OUR FORECAST IN BALTIMORE AS WELL, SCATTERED SHOWERS AND THUNDERSTORMS LIKELY TOMORROW AND SOME OF THOSE COULD DRAW HEAVY RAIN AS WELL. SOUTH OF BALTIMORE, SOUTHERN MARYLAND AND THE LOWER EASTERN SHORE, COULD BE SOME RAIN BUT MOST OF THE FOURTH OF JULY AROUND BALTIMORE WILL BE DRY AND COMFORTABLE. A BEAUTIFUL WEEKEND.
